The problem I've had with a bag or any of the tight-fitting training masks is that the oxygen inside the bag gets depleted too quickly, and makes me uncomfortable from hypoxia, long before I've had the CO2 I may need.Blossom said:...I'm going to stick with a paper bag for breathing due to the above and it is what Peat has recommended after all. ...
It's why I moved to a CO2 breathing device and normal breathing mask, so I could have a mildly reduced O2 inside the mask, which emulates altitude, and still stream in as much CO2 as I am comfortable with.
